IMPROVEMENT IN RAILWAY CAR-WHEELS.

Specification forming part of Letters Patent No. 120,985, dated November14, 1871.

To all whom it may concern:

Be it known that I, HENRY C. LocKwoon, of Baltimore, in the county ofBaltimore and State of Maryland, have invented a new and valuableImprovement in Car-Wheels; and I do hereby declare th at the followingis a full7 clear, and exact description of the construction andoperation of the same, reference being had to the annexed drawing makinga part of this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawing .is a representation of a central verticallongitudinal section of my invention. Fig. 2 is a vertical cross-sectionof the same.

This invention has relation to car-wheels; and it consists in the novelconstruction and arrangement of an elastic rim or periphery, whereby thetendency of the wheel to rattle and jolt on the rail is lessened. A i

Referring to the accompanying drawing illustrating this invention, Arepresents a railroad car-wheel, around the periphery of which I sink agroove, A', having the iianges a a' on the sides, and place therein anIndia-rubber collar, B, of equal width, but in thickness less than thedepth ofthe groove. I so form this groove that the outer face of thewheel flange a shall be nearly iush with the nearest side of the grooveA', due allowance being made for the usual bevel of said For the rim orperiphery' of the wheel A I provide a number of fellies, G, adapted insize to iit the groove A', outside the collar B, in such a manner thateach, when pressed upon, will spring or give slightly with sufficientelasticity to overcome or compensate for the slight irregularities ofthe rails or other causes, of the' rattling or jolting of the car-wheelswhen the same are in motion. Through the fellies C I cut at each end ahole, and extend the same through the rubber cushion and into the bodyof the wh eel in a radial direction. In said hole I insert a screw, D,having a tapering head to fit the opening in the felly, and near itsinner end a longitudinal key-slot, (i, adapted to receive a key, d1,employed for the purpose of securing the pin in place. rIhe holes d? andthe slots cl are elongated sufficiently to allow the pins D all therequired space for the change of posi tion resulting from the springingof the elastic fellies. E represents nuts which are placed over theinner ends of the screws D before the insertion of the keys. The nutsand keys are put in place through the apertures E', cut through the bodyof the wheels at the proper positions. These aperA tures are shaped soas to have a hat surface to let the Washers E rest against, as shown inthe drawing. The fellies C constitute the rollin g periphery of thecar-wheel, and hence are beveled and outwardly-formed, in accordancewith the usual method of con struction. The bottom of the groove inwhich the cushion B rests may be flat, but I prefer making it raised toa ridgein the middle, as shown clearly in Fig. 2, and shaping thecushion to fit it. In this way there will be greater elasticity at thesides of the cushion than between them, which will allow the i'ellies arocking motion, so as to conform more readily to the irregularitiesofthe rail-surface.

I claim as my invention- The improved railroad car-Wheel, having theelastic packing B and separated fellies C arranged within the groove A',in connection with the movable screws D, keys D', and nuts E', or theirequivalents, substantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
